The Importance of HTML Code

I believe that is important for web desingers to know HTML code even if there is great software that helps when constructing a website. The designer should at least have a working knowledge of code so that if something goes wrong with the software, they can correct it or spot the errors. The software available might be useful, but a good web desinger should understand how the program uses code to create web sites so that he or she can have greater control over their design.
